Claims. 1

The present invention relates to therapeutic treatment devices and, more particularly, to lamps designed for the treatment of body parts by administering, if desired, simultaneously radiation as well as a fluid stream to said body part or body parts.

The beneficial effect of various types of radiation upon body parts suffering from certain ailments is known. It is also known that the intensity of the irridation and the duration of the treatment required vary with the nature of the disease and that prolonged exposure of unafflicted tissues to certain rays, notably in the ultraviolet range, may be harmful.

It is, therefore, an object of the present invention to provide in a therapeutic device of the aforesaid type means permitting localized treatment of a body part, whereby the full therapeutic effect of the lamp may be concentrated upon said body part.

It is another object of the invention to provide means affording treatment of certain body parts, such as the oral, nasal or aural cavity.

It is a further object of the invention to provide means facilitating supply of a stream of irradiated fluid in addition to or in lieu of direct radiation (ultra-violet and/or infra-red).

It is yet another object of the invention to provide means for supplying a stream of irradiated fluid to be charged with additional medication useful in the treatment on a predetermined body part or parts.

It is a still further object of the invention to provide, in a therapeutic lamp, means permitting arrangement of the source of radiation in such a manner that fluid, in the form of a gas, air and the like will first be exposed to radiation before said fluid is impinged upon desired locations of the body part.

It is still another object of the invention to provide, in combination with a therapeutic lamp, means ensuring variation of the area for localized treatment of body parts, such as the ear, nose or throat; more specifically, the invention contemplates adapter means detachably and interchangeably disposed so that treatment by means of rays or irradiated air or a combination of both, may be effectuated.

It is yet a further object of the invention to provide, in a therapeutic apparatus, a combination of sources of different types of radiation which may be operated separately or simultaneously and to provide a control arrangement for energizing said sources during predetermined intervals which may be either successive or overlapping for difierent types of radiation.

The above and other objects of the invention will become apparent from the following description taken in conjunction with the accompanying drawings.

In the drawings:

Fig. 1 is a perspective view of the general organization of a therapeutic apparatus according to the invention;

Fig. 2 shows in cross section, on a larger scale, a lamp forming part of the therapeutic apparatus illustrated in Fig. 1;

Fig. 3 is a front elevation of a portion of the lamp shown in Fig. 2;

Figs. 4, 5 and 6 are fragmentary sectional views of a lamp according to the invention, illustrating various forms of adapters; and

Fig. '7 is a circuit diagram relating to the apparatus illustrated in Fig. 1.

Referring now in greater detail to the drawings and more particularly to Fig. 1, there is shown an apparatus Ii] made in accordance with the invention. This apparatus has a cabinet Il mounted on casters I2 and provided with a control panel I3; a standard I4 rising from the cabinet II; a rod I5 slidably held in a bearing l6 which is secured to the upper end of standard I4, and a lamp I! attached to the lower end of the rod I5. It will be seen that hollow standard I4 consists of two portions interconnected by a sleeve l8, whereby a rotation of the lamp-holding rod I5 relative to the cabinet II will be possible. Standard I4 encloses a portion of a cable I9 which connects lamp IT to the control cabinet I I. As shown more clearly in Fig. 2, rod I5 is provided with an extension 20 which is pivoted thereto about a screw bolt 2 I, the lamp I! being formed with a holder piece 22 which is detachably secured to the extension 20 by means of a bayonet connection 23. By this arrangement, the lamp Il may be fixed in a variety of positions relative to the cabinet II, as required for any particular purpose.

As shown in Fig. 2, lamp H has a housing consisting of a socket 24 and a cover member or hood 25. The corrugated hood 25 having an inner wall with discontinuous reflector surfaces (Fig. 2) may be detachably mounted on the socket 24 by means of bayonet connections 26, 26a and is provided with a reduced center outlet 21 and a plurality of lateral outlets 28, 28a. Each outlet 21, 28, 26a comprises an annular flange 29 designed to cooperate with an adapter, such as indicated in dotted lines in Fig. 2, preferred adapter types being disclosed in Figs. 4 to 6. Suitable covers (not shown) may be employed to close any of the outlets, when not in use.

The cable is divides into two branches, respectively, containing the wires 3t, 32 and 33 con-- nccted to a motor 38 and further the wires t l, 3%, 371 and 38, serving to supply electric current to a radiating unit indicated generally by numeral 39. The motor 36 is disposed in an extension 59 of socket 2 and carries a fan blade ll mounted on motor shaft 32. Ports d3 are provided in the socket housing 72 i rearwardly of blade ti, whereby air from the surrounding atmosphere may be drawn through openings it by the blade ll into the socket 2d and may be propelled toward the front of the socket and through one of the outlets of hood 25, if the latter is attached to the socket.

The radiating unit 39 of Fig. 3 comprises a perforated disc-shaped plate preferably of insulating material, which serves as a support for the ray-emitting elements it, it and ll. The radiating elements d5, d6 have a common terminal located at the center of the plate bl and extend therefrom in interleaved spiral convolutions toward respective terminals as and It will be seen that the elements and it occupy the major portion of the front surface of plate Radiating element t? is of annular form and is mounted adjacent the periphery of the plate is, its two terminals being shown at 5i, 52.

The insert l l may be secured to the socket 2 5 by any suitable means, such as by brackets 53.

From Fig. 2 it will appear, that wire is connected to the common terminal and that wires 3'5, 3i and 38 are, respectively, connected to terminals 5? ill and 52 (Fig. 3). The cable branch containing these five wires may enter the socket 26 by way of an insulating washer at, as shown.

In a preferred form of the invention, the ele ment ll is a source of infra-red radiation, whereas the elements 55 and it are both tubes emitting ultra-violet rays, although of different intensity. Merely by way of example, it may be mentioned that element l5 may consist of a tube provided with a quartz envelope, while the other element may be a tube having an envelope consisting of a vitreous filter material, such as is known under registered trade-mark Corex.

Referring further to Fig. '7, it will be seen that the circuit arrangement of the apparatus is may include a pair of transformers 55, a pair of timers 5?, 58 and a pair of conductors 52?, 6% con-- necting the two series combinations of a respective 'iner and a respective transformer primary to a source of electric power, such as a source of alternating current 6i. There may be further provided a simple out-out switch 52 for connecting the infra-red tube t? across the conductors and if desired, and a three-position switch for causing the motor to rotate in one or the other direction. (A rotation of motor in such a sense as to draw air through the hood 25, ejecting it through the ports 43, may be desirable ii the apparatus it is to be used as a means for random- 1y discharging irradiated air into a room with out, at the same time, exposing the eyes of an attendant or other persons present to the glare of the radiating elements.)

The operation of the circuit arrangement shown in Fig. 7 will now be clear. The timers 5% may be of any known or suitable type and serve to energize the transformers 55, 56, respectively, dur- 2t ing predetermined intervals, thereby respectively causing the elements 45, 118 to radiate.

It will be understood that the periods of energization of elements 45 and it, respectively, may be simultaneous, alternating, or overlapping, as desired for a particular treatment. The energization of element ll may be effected at will through the actuation of switch 82.

It will also be understood that, with the switch in a normal position to cause rotation of motor 30 in a predetermined direction, air irradiated for germicidal, ozonizing or other therapeutic purposes will pass through the socket 24, and, if the hood 25 is attached thereto, will escape through whichever of the outlets 27, 23, 28a happens to be open. Such outlet or outlets may be provided with an adapter or applicator designed to confine the stream of irradiated air and/or the rays themselves to a particular part of the body of the person to be treated. Various forms of adapters are shown in Figs. 4, 5 and 6. The adapter of Fig. 4 consists of a straight metal tube E l provided at one end with a head (iii, this head fitting removably but tightly within the opening of sleeve 29 surrounding the outlet. This adapter may be used, for example, for the treatment of the respiratory tract which treatment involves the inhalation of irradiated air by way of mouth.

The adapter or applicator shown in Fig. 5 is specifically designed for treatments involving in halation of irradiated air through and/or direct irradiation of the nasal passages. This adapter comprises a head -55 and a pair of tubular members E51 extending forward from said head.

Provision may be made to connect to members ill, 65 inlet pipe or pipes, such as later on referred to and designated by numeral it, for the supply of medicinal fluid (Fig. 6).

The members 58 may be partly tapered, as shown, and are spaced in such a manner that they permit convenient introduction into the nostrils of a person to be treated. For sanitary purposes, it may be desirable to provide each member fill,

with a detachable extension 69, iii, respectively, which may be reserved for the sole use of a particular patient and which can be either discarded or if made of suitable material conveniently sterilized on removal from the adapter. A similar extension may, of course, be provided for the adapter of Fig. 4.

Still another form of applicator is shown in Fig. 6. A cup-shaped member ll is inserted into the sleeve 29 and communicates, by way of a flexible tubing T2, with a similar cup shaped member it having secured thereto a tubular attachment l t. The head iii of attachment it may be similar in form to the cup-shaped memher it and is press-fitted into the sleeve member lit. The tubing l2 may consist of rubber, polyvinyl chloride or other suitable natural or synthetic material, and may be screw-threaded at its ends into cups ii and it, as shown. It will be understood that the attachment it may be replaced by other forms of adapter, such as those shown in Figs. i and 5.

One of the purposes of the provision of tubing i2 is to make it possible to discontinue direct irradiation of the patients tissues, without interrupting the flow of irradiated air through the adapter.

Thus, in the particular condition of the tubing l2 shown in Fig. 6, the patient may continue to inhale the air supplied through the hood even though no rays from the radiating unit 33 will be guided through or impinged on the attachment 14. Another purpose of the provision of this tubing is to allow for the displacement of the attachment [4 relative to the lamp H without necessitating a bodily displacement of the lamp ll, assuming that no direct irradiation of the patient is required. The flexible tubing 12, accordingly, represents a convenient means for varying the mode of treatment, as well as a flexible coupling between the adapter and the hood of the lamp.

As further shown in Fig. 6, there may be provided an inlet pipe '30 whereby additional medication, preferably in fluid form, may be introduced into the stream of irradiated air guided to adapter-attachment 14. The medication thus added may be in the form of a spray or a vapor, or it may be a liquid capable of being entrained in atomized condition by the stream of irradiated air. Ihe inhalation of the additional medication will thus occur simultaneously with any or all of the other forms of treatment afiorded by the apparatus according to the invention.

The attachment of any of the adapters to the center outlet 27 will have the result that substantially all the radiation passing through the adapter will be of the type emitted by the elements 45 and/or 40, since little or no rays from the outer element 41 will be able to reach the user by way of the tubular members illustrated in Figs. 4-6.

Yet if, in the embodiment illustrated, it be desired to subject a patient to treatment by infrared radiation, all that will be necessary will be to mount the proper attachment on one of the outlets 28 or 28a which are positioned adjacent the element '41 and to close the switch 62. It will further be understood that the latter switch, too, may be controlled by a timer such as 51 and 58 in Fig. 7.

It will be seen that the lamp [1 may also be used, if desired, in place of a conventional, widebeam ultra-violet and/or infra-red lamp by removing the hood and de-energizing the motor 30. On the other hand it will be appreciated that, even where the use of the source of air current through motor and blade 4| is not required, the attachment of the hood 25 and the closure of the unused outlet openings 28a, 28 will protect the eyes of the attendant and other persons from the rays emitted by unit 39.

It can thus be seen, that there has been provided according to this invention a therapeutic treatment plant, which essentially comprises, in combination, a socket, a radiating unit disposed in said socket, and means for localizing the therapeutic effect of the rays emitted by said unit, said means including an apertured member covering said socket and secured to the latter in front of said radiating unit.

Although the invention has been described with reference to certain specific embodiments thereof, it is to be distinctly understood that various modifications and adaptations of the arrangements herein disclosed may be made and may readily occur to persons skilled in the art without constituting a departure from the spirit and scope of the invention as defined in the objects and in the appended claims.
